Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] like figure 1 As shown, the embodiment of the present invention discloses an air compressor motor control method, the method includes the following steps:

[0057] Step S1, controlling the starting of the motor by using the set angle between the waveform of the phase current and the starting angle of the rotor position signal of the motor;

[0058] Step S2, after the motor is successfully started, adjust the angle between the waveform of the phase current of the motor and the rotor position signal of the motor to the running angle value of the motor;

[0059] The starting angle value is us...

Abstract

The present invention is applicable to the technical field of air compressors, and provides an air compressor and an air compressor motor control method and device. The method includes the following steps: using the waveform of the set phase current and the starting clip of the motor rotor position signal The angle value controls the motor start; after the motor is successfully started, adjust the angle between the waveform of the motor phase current and the motor rotor position signal to the running angle value of the motor; the device includes a motor start module, which is used to set the phase current The waveform of the motor and the starting angle value of the rotor position signal of the motor control the motor starting and the angle adjustment module of the phase current and position signal. After the motor is successfully started, the invention adjusts the angle between the waveform of the motor phase current and the motor rotor position signal to the running angle value of the motor, so that the hardware parameters can be kept unchanged, especially when the motor is difficult to start. Motor starting is more powerful and efficient.

Description

technical field [0001] The invention belongs to the technical field of air compressors, and in particular relates to an air compressor, an air compressor motor control method and a device. Background technique [0002] The existing air compressors have the following technical problems: 1. When the air pressure in the cylinder of the air compressor is high, it is difficult to start; It is also difficult to start when the voltage drop is large; 3. After a long time of use, the one-way valve in the air compressor is worn out, causing the one-way valve to leak and it is difficult to start. In order to solve the above technical problems, the starting current can be increased, but increasing the starting current needs to increase the rated current value of the power electronic device or the rated current value of the motor, which requires a large increase in cost, and the effect is not ideal. Contents of the invention [0003] An embodiment of the present invention provides a m...
